Mechanisms of Arctic amplification and Arctic climate change are difficult to pinpoint, and
current climate models do not represent the complex local processes and feedbacks at play …

Aerosol particles in the atmosphere profoundly influence public health and climate. Ultrafine
particles enter the body through the lungs and can translocate to essentially all organs, and …

With the Arctic rapidly changing, the needs to observe, understand, and model the changes
are essential. To support these needs, an annual cycle of observations of atmospheric …

Iodic acid (HIO3) is known to form aerosol particles in coastal marine regions, but predicted
nucleation and growth rates are lacking. Using the CERN CLOUD (Cosmics Leaving …

The main nucleating vapor in the atmosphere is thought to be sulfuric acid (H2SO4),
stabilized by ammonia (NH3). However, in marine and polar regions, NH3 is generally low …

Observational evidence shows the ubiquitous presence of ocean-emitted short-lived
halogens in the global atmosphere,–. Natural emissions of these chemical compounds have …

New particle formation in the Arctic atmosphere is an important source of aerosol particles.
Understanding the processes of Arctic secondary aerosol formation is crucial due to their …

New particle formation of liquid or solid nanoparticles from gas-phase precursors is a
decisive process in Earth's atmosphere and is considered one of the largest uncertainties in …

The Arctic is warming faster than anywhere else on Earth, prompting glacial melt, permafrost
thaw, and sea ice decline. These severe consequences induce feedbacks that contribute to …

Iodine is a reactive trace element in atmospheric chemistry that destroys ozone and
nucleates particles. Iodine emissions have tripled since 1950 and are projected to keep …
